Display Original Forms of Composite Solids
By default, 3D composite objects retain a history that displays an editable
image of their original component forms.
Retain the History of the Composite Components
After you create a composite object, you can modify the shape of the new
object by modifying a highlighted wireframe image of its original components.
If the Show History property is Yes (On), wireframes of the original
forms—including forms that have been removed—are displayed in a dimmed
state. (The SHOWHIST system variable also controls this setting.)
To retain a history of the original parts of composite solids, the History
property must be set to Record (On) in the Properties Inspector palette when
the composite operation occurs. (You can also use the SOLIDHIST system
variable to set this property.)
Display and Remove the History to Modify the Composite
When you modify the composite object, you can display the history. Then
use the grips on the history subobject to modify the object. For more
information about using grips with composite solids, see Modify Composite
Solids and Surfaces
on page 583.
You can remove the history of a selected composite object by changing its
History setting to None, or by entering the BREP command. After a history
has been removed, you can no longer select and modify the original, removed,
components of the solid. You can restart history retention for the solid by
changing its History setting back to Record.
